We employ data from tokamaks JET, EAST, MAST, AlcatorC-mod and COMPASS and validate it against 2D turbulence simulation HESEL.The analysis covers 500 divertor heat ux pro les with 11 varying global plasmaparameters. We see that two previously published scalings describe well only partof the database. We therefore derive 20 new scalings describing 86-93 % of themeasured decay length variability. We so-predict for attached highest current L-mode in ITER: 10-20 MW/m2surface perpendicular heat ux and twice that forCOMPASS-Upgrade.
